The Environmental Impact of Soil Pollution on Human Health
Abstract: Soils are shaped by the decomposition of rock and organic matter over several years. Soil properties vary from place to place with difference in bedrock composition, climate and other factors. Certain chemical elements occur naturally in soils as components of minerals, yet may be toxic at some concentration. Various other potentially harmful substance may end up mixing with soils through human activities. This may lead to soil contamination which in …

Estimation of Burden Rock Movement using High Speed Videography: Case Study of A Limestone Mine
Abstract: In an opencast mine involving hard rock/deposit excavation, blasting becomes a very important activity. Effective usage of explosive energy to fragment and displace the hard strata results in considerable savings. However, the occurrence of blasts in mines is so rapid that the naked eye cannot detect the process. High speed videography can provide the progress of blast in millisecond time scale needed to analyze the happenings in the blast. An …
